Serial No. 357,787. b

This invention relates to transmission means for internal combustion motors, the general object of the invention being to provide a disk to which the connecting rods of the pistons are connected and which is supported for rocking movement in a ring which in turn is supported for rocking movement in a frame, the pivotal points of the ring being arranged opposite to those of the disk, with means for transmitting the movement of the disk to a shaft.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to

be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim,

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a side viewjof the improved device. Figure 2 is an end view looking toward the cylinders.

Figure 3 is a section on line 33 of Figure 2.v

Figure 4 is a section on line H of Figure 3.

In these views, the numeral lindicates a pair of uprights supported on a base 2 and connected together by the cross pieces 3. A ring at is pivoted at two diametrically opposite points to two of the cross pieces, as shown at 5, and a disk 6 is pivoted to the ring at two diametrically opposite points, as shown at 7. Four cylinders 8, preferably of the air cooled type, are connected with one. of the uprights l, with their inner ends opening through the upright and a piston 9is arranged in each cylinder. A connecting rodlO has one end connected with each piston by the universal joint 11 and its other end is connected to the disk 6 by the universal joint 12. The pistons are connected with the disk a quarter turn from each other and the pistons are so arranged in the cylinders as to give the disk and ring a substantially gyratory movement as the pistons reciprocate in thecylinders.

, in the scope of the appended claim.

A boss 13 is formed atthe center of the disk and a rod-14 is rotatably arranged in the boss. The outer end of the rod isformed with an eye and across head 15, having a bifurcated end, is fastened to a shaft 16 journaled in the upright opposite to that which carries the cylinders. A pin 17 passes through the prongs of the cross head and through. the eye so that the cross head is pivs otally connected with the rod 14. A fly wheel 18 is connected with the outer end of the shaft 16 and a beveled gear 19 is also connected to said shaft. A pair of cam shafts 20 is rotatably supported on the upright on which the shaft 16 is journaled, each shaft having a gear 21 thereon which meshes 'with a gear 22 on a stub shaft 23, each stub shaft having a beveled gear on its inner end which meshes with the gear 19. Thus the shafts 20 are driven from the-shaft 16 and these shafts 20 "have came 24 thereon for operating the push rods 25 of the rocker arms 26 of the valves of the cylinders 8.

From the foregoing it will be seen that the reciprocatory movements of the pistons will impart a substantially gyratory movement to the'disk and its ring and this movement is transmitted to the shaft 16"to rotate said shaft through the rod 14' and the cross head 15. j I v V This arrangement permits the motor to be made much lighter than the present type of motor andenableshigh speed to be obtained' 7 with very little vibration. The friction surfaces are greatly reduced .comparedto present types of motors without weakening any of the vital parts. The arrangement of. the

cylinder makes it practical to cool the samev z, @Iby-air and eliminates wind resistance so that p the motor is usefulfor aircrafts as well as for:

motor vehicles 7 and other purposes.

It is thought from the foregoing description that thea'dvantages and novel features of the invention willloereadily apparent.

Itis to be understood that changesmay be made in the construction and in the combination and arrangement of theseveral parts, provided that such changes fall withi w I inn l/Vhat I claim is p i c A motor lncludlng a base havlng spaced uprights and one of said uprlghts carrying cylinders provided with pistons, cross memthe shaft. c

In testimony whereof Iaflix my signature."

bers connecting the uprights, a ring pivoted 'to a pair or" oppositely disposed cross menobers, a disk having a pair of pivotal connections with the ring and said pivotal connections arranged between the pivots of the ring to the cross members, connectlng rods secured to thedisk and the pistons, a boss 4- formed on and centrally of the disk, a rod rotatably carried by the boss, a power takeoff shaft journalled in theupright opposite to the upright carrying the ylinders, a head secured to the shaft and having arod eccentrically pivoted thereto for rotating the s iarl't by the reciprocation ofthe pistons, and valve means for the cylinders operated by V CARL GUNNAR-D PETERSON.
